3 Pneumococcus Vaccines: Success and Limitations × Protection is serotype specific × Efficacy was almost exclusive to invasive diseases; Bacteremia, sepsis, and meningitis × Emergence of non - vaccine type in the community × Cost and availability in LMIC × Poor protection against major infections: Pneumonia, AOM, and nasopharyngeal colonization Limitations x Introduction of the highly efficacious polysaccharide - conjugate vaccines (e.g., Prevnar series, Synflorix , etc.) reduced pneumococcus infections dramatically Success Problem: Pneumococcus causes serious diseases (e.g., acute otitis media, sinusitis, pneumonia, bacteremia, sepsis, meningitis, etc that cause high morbidity and mortality in children and elderly Moffitt &Malley, 2016 Daniels, C.
